President Donald Trump was so angry and concerned his first nominee to the U.S. Supreme Court would not be loyal or conservative enough, he considered revoking his nomination, The Washington Post reported Monday.

The Post cited 11 sources, some who spoke only on condition of anonymity, but others disputed the characterization the president would have withdraw Neil Gorsuch from nomination.

The source of Trump's ire, according to the Post's sources, was Gorsuch's statement to Democratic Sen. Richard Blumenthal that Trump's criticism of federal judges was "disheartening" and "demoralizing."

That comment caused Trump to worry about Gorsuch's loyalty, the Post quoted one source, and he angrily stated he knew plenty of other judges who would jump at a chance at a lifetime appointment to the nation's highest court.

But Trump's anger could simply have been venting, as he often does, the Post noted, though many staffers did fear Gorsuch might just might get the plug pulled on himself.

Officials told Trump that Gorsuch was simply demonstrating his independence, which was necessary for the Supreme Court justice.

Trump also seemed assuaged by a letter written by Gorsuch on March 2, but he did not receive personally until March 10, which praised Trump's state of the union speech.

"Your address to Congress was magnificent," he wrote. "And you were so kind to recognize Mrs. Scalia, remember the justice, and mention me. My teenage daughters were cheering the TV!"

Legislative affairs director Marc Short passed the letter on to Trump.

"As head of legislative affairs, our team was in charge of his nomination, and never did I view his nomination in jeopardy, nor did the president ever suggest to me that he wanted to pull him," Short told the Post. "The process obviously caused frustration, but that frustration was compounded by the fact that Gorsuch had sent him a personal letter that he never received."

Gorsuch was confirmed by the Senate in early April on a nearly party-line vote of 54-45.
